New for 2014! The Hydro Cell replaces the Hydro Stick or Silver Stick and is compatible in all humidifiers that use the Hydro Stick or Silver Stick. The new Hydro Cell is placed into the water tank instead of inside the base of the humidifier.

The AIROSWISS Hydro Cell AOS A200 (replaces Hydro Stick and Ionic Silver Stick) is an advanced water maintenance system with activated carbon technology to provide constant freshness in AIR-O-SWISS Humidifiers and Air Washers. The Hydro Cell is simply placed inside the water tank, and begins working as soon as it comes into contact with water, even if the humidifier is turned off.
